矿坑涌水量预测计算探采对比研究

Comparative study on estimating and calculation of mine water yield during exploration and mining

固体矿产勘查、开采中,矿坑涌水量的计算和评价,对促进以及提高各类矿区水文地质勘查工作质量,科学合理估算矿坑涌水量有重要意义。但矿山生产实际中,矿坑涌水量实际有时会出现与预测计算涌水量出现偏差的情况,给生产安全带来一定的不利影响。本文通过调研收集典型生产矿山矿坑排水资料,结合地质勘查中矿坑涌水量预测计算结果,总结矿坑涌水量预测计算中常用的方法及其与准确性的关系,并分析了计算值与偏差之间的原因,给出了相关的建议。

During solid mineral exploration and mining,the calculation and estimating of mine water yield is significance to improve the quality of hydrogeological exploration in various mining areas and to estimate mine water yield reasonably.However,during mining,the actual mine water yield sometimes deviate from the estimated ones,which may affect mining safety.Based on the investigation and collection of drainage data of typical mines,combined with the calculation results of mine water yield estimating in geological exploration,this paper summarizes the commonly used methods of mine water yield estimating and its relationship with accuracy,analyzes the reasons between the calculation value and the deviation,and gives relevant suggestions.
